BITMAPFILEHEADER

The BITMAPFILEHEADER structure contains information about the type, size, and layout of a file that contains a device-independent bitmap (DIB).

typedef struct tagBITMAPFILEHEADER { // bmfh 
    WORD    bfType; 
    DWORD   bfSize; 
    WORD    bfReserved1; 
    WORD    bfReserved2; 
    DWORD   bfOffBits; 
} BITMAPFILEHEADER; 
 

Members

bfType

Specifies the file type. It must be BM.

bfSize

Specifies the size, in bytes, of the bitmap file.

bfReserved1

Reserved; must be zero.

bfReserved2

Reserved; must be zero.

bfOffBits

Specifies the offset, in bytes, from the BITMAPFILEHEADER structure to the bitmap bits.

Remarks

A BITMAPINFO or BITMAPCOREINFO structure immediately follows the BITMAPFILEHEADER structure in the DIB file.
